How to Build Redstone Logic GatesLogic gates are redstone circuits that give a different output based on their own

rules. For example, the output from an AND gate will only be active (turned on)

when both its inputs are active.

NOT gates

A NOT gate will invert the input it gets. So if you connect the input with a lever,

turning the lever on will cause the NOT gate to output a signal that is turned off.

AND gates

An AND gate takes 2 inputs and will only send out an active signal if both inputs

have been activated. So if you’ve connected both inputs to a lever, turning on

just 1 lever will not activate the mechanism connected to the AND gate’s output.

NAND gates

A NAND gate is basically the NOT gate equivalent of the AND gate. Instead of

sending an active signal when both its inputs are active, the NAND gate willdeactivate the signal its sending out. Turning on just 1 level will not deactivate

the mechanism connected to the NAND gate’s output.

OR gates

This is very easy to figure out by just looking at the picture. If any of the inputs

are turned on, the mechanism connected to them will also turn on. Only when

all of the inputs have been turned off will the mechanism turn off.

NOR gates

The NOR gate is almost the exact opposite of the OR gate. If any of the inputs

are turned on, the mechanism connected to them will turn off. Only when all of

the inputs have been turned off will the mechanism turn on.

XOR gates

The XOR gate will only send out an active signal when only 1 of its inputs is

active (when both inputs are different). If both its inputs are active or

deactivated, the mechanism connected to the XOR gate will also be

deactivated.

XNOR gates

The XNOR gate will only send out an active signal when both its inputs are the

same (on or off). If just one of the inputs is active, the mechanism connected to

the XNOR gate’s output will deactivate.

Implies gates

The implies gate is a bit tricky to fully understand. You can see it as a master

switch and a child switch. In the example below, lever A is the master switch.

Turning A on will deactive the piston, turning it off will activate the piston.

However, as long as lever A is turned off, lever B will not function. Once lever A

has been activated, lever B can turn the piston on and off.

We can make it a little more complicated, like this:

In the picture above we’ve added another piston. As long as lever B is turned

off, lever A can turn both pistons on and off at the same time. But when lever B

is turned on, lever A can only turn piston 1 on and off. The old rules for lever B

are still true. Lever B can only turn piston 2 on and off, but only if lever A isturned on.
